1 ViDe, Internet2, GDLN and Europe Markus.Buchhorn@anu.edu.au Australian National University

2 ViDe www.vide.net Video Development Initiative An activity of SURA to support member Universities (and beyond) Many projects/working groups

3 ViDe activities Strong interest in video conferencing (H.323 mostly) and video-on-demand issues Deliverables Videoconferencing Cookbook ViDeNet A globally coordinated H323 infrastructure, and recently deployed MCUs in Canada, Australia and Netherlands Work on standards and services

4 ViDe projects VideoAccess WG Standards for video metadata in DC, MPEG7, RDF Rights-L Digital Rights Management, ORDL, XRDL, MPEG-7, … MPEG-4 WG Microsoft Exchange VCS Video Conferencing, and Addressing Data Collaboration Scout (analysis)

5 ViDe “Spin-off” The MegaConference (1,2,3) 200 sites worldwide (and beyond!) using H.323 Tree of MCU’s Delivering virtual conference tracks, virtual quartet, and virtual picnic Became very useful after 11 Sept…

6 Internet2 Many activities described Internet2 Commons VidMid working groups Access Grid (Ok, not I2, but NCSA)

7 Internet2 Commons Deliver an I2-wide infrastructure/service, based on ViDe designs and experience Large scale MCUs at OSU Training services

8 VidMid Middleware for video Combination of I2 Middleware WG and ViDe members, and others VidMid-VC: Video-conferencing (H.323, SIP, others) VidMid-VoD: Video-on-demand Issues of: Security Authentication, authorisation and accounting Directory Services …

9 Access Grid NCSA Grid project Multicast-based, “high-quality” videoconferencing “Integrated” with presentation tools and good quality audio Extensions to collaborative virtual environments Can support many sites simultaneously (30+) with multiple streams from each (5+), and groups of any size at each site.

10 Global Development Learning Network A project of the World Bank Support the delivery of content into developing countries Content comes from (goes to) Govt, NGO’s, Universities, … Content from around the world Includes policy development, distance education, negotiations Multilingual Cost recovery – self-sustaining.

11 Where is it? Africa: Benin, Cote d’Ivoire, Ethiopia, Ghana, Senegal, Tanzania, Uganda East Asia and Pacific: Australia, China(2), Korea, Singapore, Thailand, Vietnam Europe and Central Asia: France, Spain, Turkey, Ukraine

12 Where is it? (2) Latin America and the Caribbean Bolivia, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Nicaragua, Peru Middle East and North Africa Egypt, Jordan North America Canada, Mexico, USA (2)

13 How is it done? 3 satellites (Asia-Pacific, Americas, Europe-Africa) WB Fibre links between the ground- stations Digital/Distance Learning Centres (DLCs) connected by own satellite dish, or fibre to remote satellite dish

14 How is it done? (2) DLCs are videoconferencing centres (synchronous activities) and PC labs (asynchronous activities) Support video, data and voice, 256-384kb/s, symmetric. Video is done with H.320 mostly (ISDN/serial based), although some IP gateways. Multi-site events supported through bridge/MCU in Washington 5-10 sessions/day, 18 hours/day.

15 Where is it going? IP, on the ground and maybe on the satellites Potentially more use of existing infrastructures (APAN, I2, …) – or else it will happen anyway More sites, more remote locations, much more content. 100 DLCs by 2005

16 Europe Various Task Forces One in streaming video Which collaborates with ViDe and VidMid And it’s not just about streaming Interest in high-quality video-conferencing ATM codecs very popular – led to ATM/IP development… High resolution, high frame rate, … A lot of MPEG2 developments See also U.Wash/Sony collaboration on HDTV/IP Lot of usage for distance education

17 Europe VRVS Very popular in Physics community Came from CERN Supports multicast, gateways into unicast Supports various A/V codecs over rtp Gateways into H.323, SIP and Access Grid (and others as they are invented…) Virtual-Room based for grouping

18 And closing the circle… The World Bank is meeting with ViDe and I2 to explore options Maybe connect Washington WB HQ to Abilene? Europe connected to US over 2.5Gb/s link(s) VRVS used as glue for various network A/V projects

19 Many Asian activities I have not covered Asian activities due to lack of time, but… MY – MCS KR - HAT and MCONF JP – MPEG4, MPEG2 SG – H.323, iVCNet AU – VoIP, H.323, SIP, HQ-Video, …

20 Many technologies… Let’s talk later…
